SOFA-BED OF THE DAVENPORT STYLE.

Specification of Letters Patent.

Patented June 4, 1912.

Application filed January 4, 1912. Serial No. 669,361.

To all whom it may concern:

Be it known that I, HARRY CHnssLER, a citizen of the United States ofAmerica, and a'resident of New York, county and State of New York, haveinvented certain new and useful Improvements in Sofa-Beds of theDavenport Style, of which the following is a specification.

This invention relates to novel sofa-beds of the davenport style. Duringday-time such acombination sofa resembles an ordinary sofa in appearanceand occupies relatively small space, while at night it may betransformed into a bed, usually by unfold- Tt is the special object ofthis invention to produce a convertible sofa which is provided withmechanism to turn over the seat and simultaneously move the back andplace it side by side with the seat. Accordingly the transformation ofthe sofa into a' bed is accomplished by one simple operation andmattresses may be provided on the rear of the back, which are alsoturned down by the single operation of the device, so that the entiretransformation may be effected in a few moments. The mechanism fortransforming the sofa. into a bed is of such construction that it formstwo bottom supports or feet at each side of the sofa.

In addition to the above main advantages, it has been sought to producean article that is an ornament to a room. The operative mechanism is sosimply constructed and occupies so little space that there is noindication whatsoever of same in the finished sofa, and the increase inthe cost of production is accordingly so slight as to be negligible inan article of this kind.

In order to make the invention entirely clear, reference is made to theaccompanying drawing, in which:

Figure 1 represents somewhat in perspective view a sofa-bed of thedavenport style. Fig. 2 illustrates the inner box frame in sideelevation with back and seat in the same position as in a sofa, and Fig.3 shows in side elevation the inner box frame with back and seat as in asofa-bed.

Similar characters of reference denote like parts in all the figures.

In the drawing A, B, C represent the frame of the sofa-bed, which coversthe inner box frame D, while E is the back of the frame. The brackets Fshown in Figs. 2 and 3 are secured in the rear portion of At each sideof the front portion of the I sofa-bed a hinge I is provided, one memberof which is secured to the frame D near its front end and the othermember to the bottom end of the seat.

For the purpose of converting the sofa into a bed by one movement oroperation, two connecting braces J are secured one at each side. Thisconnecting brace J is of peculiar shape, it is substantially S-shaped,as shown, and connected to the seat and back in well defined locations.One end of said brace-is connected by means of a pivot K to the back,somewhat beyond the middle and near the rear side, as shown. Near thebottom-end portion of the back the brace is curved and-continues atpractically a right angle to the first described portion to near the topsurface of the seat. Near the middle portion of the seat there is asecond slight curve in the brace and at the end of same a second pivot Lsecured in the seat. The brace continues in a straight line to thebottom surface of the seat and then forms a slight curve and extendsdownwardly for a certain predetermined length. The brace as described isin the location found in the sofa-bed when same forms the sofa, as shownin Fig. 2. Two mattresses M, N, are held in position on therear of theback. The mattresses are connected at their inner ends and the mattressresting on the rear side of the back is held in position by means of twoshort braces at each side. The second mattress is held in position bymeans of two somewhat longer braces P at each side, extending from thefree end portion of same over to the sides of the back.

To facilitate the working of the operative mechanism, the grip Q, issecured to the rear side of the seat in. the center. When this grip ispulled up, the seat moves on the hinges I and the pivot L by virtue ofthe connecting brace J, which moves on said pivot in the direction ofthe semicircle and the arrow shown in Fig. 2. Simultaneously the backmoves on the pivot K in the arc of a circle with arrows, shown in dottedlines in Fig. 2. As soon as both the back and the seat assume ahorizontal position side by side as shown in Fig. 3, the turningmovement of same is at an end because the connecting brace J is soconstructed as to form a support or foot by means of the large curvedportion R, which rests on the floor. Furthermore, the end portion S ofsaid brace extends downwardly from the seat and is ,of such length as toform a second support or foot, as shown in Fig. 3. In this manner twosupports or feet are formed at each side of the sofa when same has beentransformed into a bed. Now the holding braces O and P of the mattressesare released and the mattress N placed over the top side of the seat.

' position, shown in Fig. 1.

Thus the sofa may be transformed into a double bed by one simpleoperation in a few moments. As described, this is effected particularlyby means of the peculiar construction of the connecting braces J, thehinges I and the pivots L, K. The entire operative mechanism forms apermanent part of the sofa and, therefore, nothing can be lost ormislaid.

In order to transform the double bed again into a sofa, the mattress Nis secured. to the back. Then both the back and seat are moved bypulling the grip in an upward direction until both assume their originalIt is evident that the form of the connecting brace, the location of itspivots and of the hinges on the seat and back are important features forattaining the desired results in a quick and reliable manner. Themattress, however, and the other details may be arranged in variousmanners without de parting from the spirit of the present invention.

I claim 1. A sofa-bed convertible by a single movement comprisingessentially a frame, a

- seat and a back, and two substantially S- shaped braces one on eachside, a pivot attaching one end portion of each brace cen trally to aside of the back, a pivot attaching a second bent portion adjoining thecenter of the seat to same, and ahandle in the rear center portion ofthe seat'whereby the back and seat are simultaneously moved toward theoperator when forming a bed out of the sofa.

2. A sofa bed convertible by a single movement; comprising essentially aframe, a seat and a back, supporting brackets for the back, two pivotsin the rear bottom end portion of the back connecting with saidbrackets, two hinges connecting each a frontbottom portion of the seatand the frame, and two pivotally secured substantially S- shaped bracesconnecting the back and seat and forming feet when a bed has 7 beenformed.

3. In a sofa-bed a movable seat and back, two substantially S-shapedbraces one at each side of said seat and back, a pivot in each side ofthe back engaging one end portion of said brace, a second pivot inapproximately the middle of the side of the seat engaging the adjoiningportion of the brace, and a handle in the rear portion of the seat bywhich the back and seat are movable in one operation, said braces beingso shaped as to form two feet when the sofa has been transformed into abed.

4. In a sofa bed operative mechanism for converting same by onemovement, comprising essentially two substantially S-shaped bracesconnecting said back and seat each consisting of a straight rear portionwith its end pivotally connected to the side of the back, a portioncurved at about a right angle thereto, a second straight portionpivotally secured to the side of the seat, and a slanting end portion,said first curved and said end portions being adapted to form feet whenthe sofa has been transformed into a bed.
